Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a reflectarray antenna unit, a reflectarray antenna and a manufacturing method. Background technique [0002] The microstrip antenna is a form of antenna that appeared in the 1970s. As early as 1953, Deschamps proposed the concept of using the radiation principle of the microstrip line to make a microstrip antenna. It was not until the theoretical model of microstrip transmission and the development of lithography technology on copper-clad dielectric substrates that scholars such as Munson and Howell developed the first batch of practical microstrip antennas. After the 1970s, the microstrip antenna has been further developed both in theory and in the breadth and depth of application, and has shown its great potential in practical application. Microstrip antennas of various new forms and performances are constantly emerging, and are widely used in military fields such ...
